摘要: 【目的】分析新疆南北疆马泰勒虫感染的差异性及地方流行株遗传进化距离,研究马泰勒虫遗传多样性及其感染率。【方法】采自南北疆478份疑似马匹的血样,经马泰勒虫PCR方法检测,分析马泰勒虫感染情况并应用最大似然法(ML)基于18 S rRNA基因的遗传进化树及构建系统发育树。【结果】在所采集的样品中,中国新疆北疆地区马泰勒虫感染阳性率为13.96%(25/179),中国新疆南疆地区马泰勒虫感染阳性率为27.09%(78/299)。印度、南非、西班牙、伊朗等地方株聚为一支,扩增的18S rRNA基因(MF398476、MF398477)与瑞典地方株聚为一支。【结论】中国新疆南疆马泰勒虫感染率高于北疆,南北疆马泰勒虫感染存在显著性差异(P=0.001<0.05),在不同年龄段马匹的感染无显著性差异(P>0.05);扩增的马泰勒虫阿勒泰、托克逊地方流行株(MF398477、MF398476)与瑞士地方株(KM046918.1)亲缘关系最近。

Abstract: 【Objective】 To understand the situation of Theileria equi and the genetic distance of local endemic strains strain of Theileria equi in Xinjiang.【Method】478 horse blood samples were collected from Southern and Northern Xinjiang, and Equine Theileriosis was investigated by PCR, the 18S rRNA gene was analyzed and the phylogeny tree was constructed based on Maximum Likelihood algorithm.【Result】The result showed that the infection rate in Northern Xinjiang was 13.96% (25/179), and the infection rate in Southern Xinjiang was 27.09% (78/299); It was thought that the strains in India, South Africa, Spain, Iran and other places clustered into one branch and the strains with the genes (MF398476, MF398477) and Swedish local strains clustered into another branch.【Conclusion】The infection rate of Equine Theileriosis between Northern and Southern Xinjiang displayed significant difference(P=0.001<0.05),but there was no significant difference(P>0.05)in different age groups. The amplified Theileria equi in Altay and Tuokexun endemic strains (MF398477, MF398476) and the local strains of Switzerland (KM046918.1) had the closest relationship. The test provided a data to support the control of Equine Theileriosis and the accurate classifying status of Theileria equi.
